TEMPERED GLASS

FULLY TEMPERED GLASS ( TOUGHENED GLASS ):

Fully Tempered Glass "popularly known as toughened glass" is made of annealed glass. It is 4 to 5 times stronger than an annealed glass & twice stronger than a heat strengthened glass.

The fully tempered glass is heated to its softening point temperature of 600 - 700 degree celsius then it is moved for quenching. The quenching begins at a glass temperature of 400 - 500 degree. The quenching causes compression on 20 percent surface area of glass and edges remaining 60 percent middle part develops stress zones as a result glass becomes stronger on surface and edges providing freedom to applicators for end to end fixing of glass using spider fittings or other accessories used for glass glazing.

On breaking a Fully Tempered Glass shatters in to small size oval shaped pieces having blunt edges thus reducing possibility of human injury to a big extent. It is widely used where human safety is concerned.
